PRINTING ATTACHMENT FOE SLOT-MACHINES.

I Specification of Letters Patent.

Patented Feb. 17, 1915a State of Ohio, have in-Ventedcertain new anduseful Improvements in Printing Attachments for Slot-Machines, of whichI declare the following to be a full, clear, and exact description.

This invention relates to improvements in amusement devices and hasmoreparticular relation to improvements in coin or check freed devices.i

Th object of the invention is to provide a machine of the classmentioned with a recording mechanism whereby thedifi'erent results maybe' recorded at will for future reference. With this and incidentalobjects in view,

the invention consists in certain novel fea-- tures of construction andcombinations of parts, the essential elements of which are set forth inappended claims and a preferred form of embodimentofWhic-h ishereinafter specifically described with reference to the drawings whichaccompany and\form part of this specification.

Of said drawings: Figure 1 represents a transverse vertical sectionthrough a machine embodying my invention. Fig. 2 represents a detailperspective view, partly broken away, of the interlocking frame.

Fig. 3 represents a detail perspective view, partly broken away, of thecoin actuated latch. Fig. 4 represents'a top plan view, partly insection, of the devices embodying this invention. Fig. 5 represents adetail top plan view of therecordv strip and the ink ribbon feed rollersand connections.

In machines of the class shown in this invention, it-is customary tohave indicators representing; playing cards, numbers,

dows by the operators'of the machine. In

other words any one using the apparatus may state that certaincombinations have come to the windows upon his operation of the machinewithout this being a fact as there are no means for proving just whichcombinations are presented to View at the char I cter faces similar todice and other charac-- indicator windows. The present invention,however, 1s designed to obviate this dif culty and to print a record ofany combination desired. which may have been indicated at the indicatorwindows. Tn providing mechanism for printing these differentcombinations, I have so constructed the same that only one impressioncan be taken from any set group of types'between each operation of themachine proper. I have also provided means whereby no impression can betaken from the types while the type and emblem carrying drums or disksare moving. The detail description of these several mechanisms is asfollows: A series of indicating wheels 1 bearing indicia resemblingplaying cards is loosely mounted upon a transverse shaft 2 which issupported at its ends by the cabinet 3 of the machine. Attached to oneside of each indicator is a type carrier 4 bearing characterscorresponding to those of the indicator. Surrounding the shaft 2 andprojecting from each type carrier is a short sleeve 5, which has securedto its outer end a ratchet wheel 6. Loosely mounted upon each sleeve isa pinion 7 which carries a pawl 8 that engages the teeth of the ratchetwheel 6. A series of vertical rack bars 9 mesh with the pinions 7 andare guided in their vertical movement by a transverse bar 10. A shouLder 11 formed upon each of the racks 9 contacts with the underside ofthe bar 10 and thereby limit-s the upward movement of said rack. Coilsprings 12,0ne. for each rack bar 9, have their ends connected to pins13 projecting from the bars 9 and hooks 14 extending from the undersideof the trans verse bar 10 thereby holding the racks in an upwardposition. Pivotally connected to the lower end of each rackbar 9 is apawl 15 provided with a shoulder 16 and an inclined forward edge 17.Each pawl is provided with an upwardly extending portion 18 which isnormally forced into contact with a pin 19 projecting from each rackbar, by a spring 20 wh1ch surrounds the v the shoulders 16 of the pawls'lowers all of the rack bars,

cabinet 3. When the handle 23 nears the end of its downward movement,the inclined forward edges of the pawls 15 contact with a transverse rod24 and are forced out of engagement with the rod 21, thereby ermittingthe springs 12 which are of di erent strength, to suddenly raise therack bars 9 and by means of the pinions 7, pawls 8 andthe ratchets 6rot-ate the indicators 1. The momentum gained by the indicators in theupward movement of the racks 9 is sutficient to cause them to rotateafter the racks and pinions have come to rest. Light leaf springs 25secured to the transverse bar 10 extend upwardly and engage star wheels26 fastened to the indicators .to properly aline same. The operatinghandle is normally locked by a hook pawl 27 which engages with a pin 28projecting from one of the arms of the frame 22 and is arranged to bereleased by the weight of a coin inserted through a slot 29, andcontacting with a lateral projection 30, see Fig. 3, of the pawl 27 androcks the hook end of said pawl out of engagement with the pin 28. Thepawl 27 assumes the position shown in Fig. 2, by gravity and is limitedin its movements by pins 31. The coin when deposited, rests upon aflange 32 of an upward extension of one of the side arms of the frame 22and against the extension 30 of the pawl When the handle 23 isdepressed, the coin slides 0d of the flange 32 and drops tothe bottom ofthe machine from where the accumulated coins may be removed at anydesired time by the attendant through the back of the cabinet which ishinged as at 33 and held in closed position by a lock 34. The frame 22is returned to normal position by a spring 35 connected at one end toone of the side arms of the frame 22 and at its other end to atransverse shaft 36.

It is understood in this style of machine that certain combinations thatmay appear under the window 37 formed in front of the cabinet 3 areconsidered as of greater value than others. Heretofore, in machines ofthis class it has been possible for the operator falsely to claim thathe displayed certain combinations after these combinations have beendisarranged, but by the following described printing attachment, apositive record is made of such combinations as desired. When a certaincombination appears beneath the window, the attendant is notified and heoperates a lock 38 located in the front of the casing to withdraw itsplunger 39 from engagement with a lug 40 projecting upwardly from aplunger rod 41. This rod, which extends through the front of the casingand. is provided with an en- 'larged head 42, is then pushed inwardly bythe attendant against the tension of its ries an anti-friction roller 43which con- At its inner end the rod car tacts with a shoulder 44 formedupon a pivoted pawl 45 mounted upon the right-hand one of a pair ofupright arms 46. These arms are pivoted upon a shaft 47 and areconnected at their upper ends by a transverse rod 48 upon which aresupported two arms 49 connected at their upper ends'by a bar 50.Inserted in the front of this bar and directly behind the type carriers,are rubber impression blocks 51, one for each type carrier 4. The arms49 have tails 52 which are normally held in contact with pins 53 securedto the arms 46 by leaf springs 54 which are secured at one end to thearms 46 and at their free ends contacting with the forward sides of arms49. It will be seen that as the rod 41 moves i11- wardly, the entireframe composed of arms 46, rod 48, arms 49 and bar 50 will be rockedabout the shaft 47 until the pawl 45 is cammed downwardly out ofengagement with the roller 43 by the inclined portion 55 of said pawlcoming into contact with a stud 56 projecting inwardly from the side ofthe casing. The frame will then be drawn forward by spring 57 until thearms 46 are arrested by pins 58 projecting from the easing. This suddenarresting of the arms 46 will cause the arms 49 to move farther forwardagainst the tension of the leaf springs 54 until the impression blocks51 take an im. pression upon a record strip 59 through a ribbon 60 fromthe type carriers 4, after which the parts will return to the positionshown in Fig. l. A coil spring 61 keeps the pawl 45 in contact with theprojection 56. The lower rearward end of the pawl 45 is provided witharoller 62 which engages with the rear end of the record strip feed pawl63, so that when the pawl 45 is depressed the pawl 63 will be rockedabout its pivotal point 64 located in the upper end of an extension 65of one of the arms of the frame 22. This extension 65 is provided withlateral projections 66 in which is mounted a spring "pressed plunger 67which engages with notches 68 formed upon the underside of the pawl 63and hold said pawl in either of its adjusted positions. As the pawl 63is rocked about its pivotal point 64 by the pawl 45, the forward end ofsaid pawl passes by the teeth of a ratchet wheel '69 which is secured toa shaft 70 to which is secured one end of the record strip 59. The pawl63 is limited in its downward move ment by a 'flange 65* of theextension 65. When the frame 22 is depressed by the handle 23, the pawl63 moves in an arc of a circle described from the center of the shaft 22and engages the teeth of the ratchet wheel 69 and moves it andconsequently the record strip, one space. Near the end of the downwardmovement of the frame 22 the rear end of the pawl 63 contacts with astud 71 projecting inwardly from the casing 3 mamas bon 60, It will beseen from this construc-- tion, that when the record strip is fedforward, the ribbon will lso be fed, thereby bringing a new inkingsurface to the printing point. The record strip 59 is fed from a supplyroll 75 over guide pins 76 to the shaft 70, while a ribbon 60 is fedfrom a supply roll/77 over guidapins 78 to the shaft 7 Attached .to eachindicator 1 on the side opposite the type carrier 4; is a toothed wheel79, which is engaged by a pawl 80 centrally pivoted upon the shaft 36.These pawls are fastened together by a bar 81, see Fig. 2, and a similarbar 82 behind and in front of their pivotal points respectively.' lhesepawls and bars constitute a locking frame which, when the indicators arerotating, will lock the push rod 41 by the bar 82 rising in the pathof-a downward projection 83 of of the frame in both ing drums inposition u rather said rod and in turn will lock cators when the rod 41is operated by the projection 83 passing'over the bar 82. This frame isso balanced that the rear ends of the pawls. 80 engaging the teeth ofwheels 7 9 offer very little resistance to the rotation of theindicating wheels 1. ()neof the arms of the frame 22 has a downwardextending portion 84 equipped with teeth 85 with which a spring drawnpawl 86 is arranged to engage to insure the full stroke directions andthereby prevent any manipulation of the indicators 1. i

It will be seen from the foregoing that by varying the tension on therack springs,'the momentum drums may be irregularly rotated upon theactuation of the operating lever and such an irregular movement given tothem as to prevent any possibility of predetermining the combinationswhich will finally come to rest in front of the indicator windows. Itwill be further seen that it is only necessary to, feed the detail stripforward after the printing of one of the displayed indications has takenplace and that this printing is effected only when such com-.

binations come to View as might be termed winning combinations. Duringthe time that the-emblem carrying drums are rotatinwar .-;VVhen thekeyisfinally operated,

it looks and alines all o flthe emblem carryntil the key is again normalposition. i

rovided with a key permitted to resume its have shown this key ascontrolled look so that t e printing may be accomplished by the owner ofthe machine than by the. operator, but this of .7 6.

the indicourse is optional as the key and lockmay be readily omitted andthe operator permitted to make impressions of the characters exposed atthe indicating windows. The arrangement of the indicating characters andthe printing types is such that when certain characters are exposed atthe windows the corresponding characters are in printing line adjacentthe platen While I have shown my invention as applied to the type ofmachine containing mo-- Inentum. indicators, it will of course beunderstood that do not care to limit myself to such construction, as theinvention with.

equal facility may be applied to the indicating mechanism operated totake up different set positions by any desired form of operatingmechanism,

Vfhile the form of device here shown and described is admirably adaptedto fulfil the objects primarily stated, it is to be understood that itis not desired to confine the invention to one form of embodiment heredisclosed, for it is susceptible of embodiment in various forms, allcoming within the scope of the claims which follow.

Having thus described my invention, what ll claim as new and desire tosecure by Letters Patent is: .i

1, In a machineof the class described, the combination with a series oftype carriers, of a platen, a special key for operating the platen andmeans requiring a movement of the type carriers sions therefrom,
